When Amy discovers that a horse named Spartan is being abused, she convinces her mother to rescue the horse and bring him back to Heartland. On the way home a raging storm sends their truck and horse trailer careening off the side of the road, killing her mother. Grandpa Jack helps Amy find the strength to stop blaming herself and begin the process of healing Spartan, and healing her own heart.

When Lou's boyfriend arrives at Heartland the question on everyone's mind is, how long is he staying? Carl has been offered a lucrative position at a firm in Chicago and he's come to Heartland to convince Lou to go with him. Everything seems to fall into place when Lou is offered a job at the same Chicago firm. Meanwhile, Amy and Mallory have discovered Scott is secretly in love with Lou and it turns out all is not right with Lou's job offer.

Lou has no intention of playing mid-wife to the pregnant mare, Melody, but Grandpa Jack insists she stay. With Ben away at a jumping show and Jack and Ty at a cattle roundup, Melody goes into labour. Lou calls in an eccentric old neighbour who uses traditional remedies to heal horses to help with the delivery.

Prize-winning rider Nick Harwell stops by Heartland. Mallory discovers a crooked ranch-hand who plans to sell a herd of wild mustangs to a slaughterhouse.

The pressure is on when a famous race horse, Gallant Prince, is sent to Heartland to see if it can be rehabilitated. The horse has been terribly burned and injured in a highly published stable fire. Its physical scars have healed but the mental ones remain. Lou makes the mistake of talking to a reporter and soon all eyes are on Amy and her "gift".
